Aruba Weather & Climate

Key West Weather

Perhaps the best aspect of vacationing in the tropical paradise of Aruba is the excellent year 'round weather. Aruba's proximity to the Equator keeps the weather warm throughout the year. No matter what time of year you visit this Caribbean island, you'll find clear sunny skies, warm temperatures, relatively low humidity, lovely refreshing trade winds, and very little rain. With less than twenty inches of average rainfall, you are sure to enjoy some sunny days on the beach or on the water.

Although Aruba is located in the Caribbean Sea, it is virtually unaffected by the Atlantic hurricane season, unlike other vacation destinations in the northern Caribbean and the Mexican coast. Combine this perpetual sunny weather with an average daytime temperature of eighty-two degrees (Fahrenheit) and you have the perfect weather for a tropical vacation destination. The leeward coast of Aruba is generally well-protected from winds and rough seas, allowing for calm weather and excellent visibility for Scuba Divers.

Winter

Daytime highs reach the middle to upper eighties and nighttime lows average in the mid seventies (Fahrenheit); you will not find a more idyllic destination to escape those winter blues. November and December are the rainiest months of the year, but in a place where the average annual rainfall is around sixteen inches, you won't have to worry about any extended deluges ruining your beach day or fishing outing; in Aruba, when it does rain, it tends to come in short sporadic showers. The water temperature ranges from the upper seventies to the low eighties (Fahrenheit), Scuba Divers may want to utilize a light suit (some may simply use a shorty or skin). On the windward coast of the island, Windsurfers and Kite Surfers will appreciate the perfect wind conditions from January through March. If you are interested in some Deep Sea Fishing, winter is the peak season for Billfish like Blue Marlin White Marlin and Sailfish off Aruba.

Spring

High temperatures in the spring tend to hover around ninety to ninety-one degrees (Fahrenheit), while the lows descend to the upper seventies. Water temperatures begin to rise towards the eighties this time of year. Winds tend to pick up during May and June. If you are looking to hook a prize Albacore Tuna or Bonito, both of these game-fish species begin to become active off Aruba in the spring.

Summer

This is the hottest part of the year in Aruba; daytime highs consistently hitting the low nineties (Fahrenheit) and the nighttime lows staying above the eighty degree mark on the thermometer. The water temps climb to around eighty-two degrees. June through November is the Atlantic Hurricane Season, but you won't have to worry when visiting Aruba - the island is rarely affected by hurricanes or tropical storms, unlike other Caribbean islands like the Bahamas. If you are into Offshore Fishing, Mahi Mahi (also known as Dorado or Dolphin) tend to ramp up in July while Sword Fish begin to run well in August.

Fall

High temps stay in the upper eighties, while the average low temperature hovers around seventy-eight degrees (Fahrenheit). The water remains in the eighties until late autumn. This is the height of the stormy season in the Caribbean, but due to Aruba's southwestern location, it is rarely affected by these storms. Yellowfin Tuna and Billfish, such as Marlin and Sailfish, begin to become active off Aruba this time of year.
